BUTTERMILK-COOLER.

To all whom it may concern:

Be it known that T, Gnoncn V nny, a citizen of the United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Buttermilk-Coolers, of which the following is a specification.

My invention has for its object to provide 1 a refrigerating container for buttermilk or} I i shoulder formed around the outer bottom The container comprises an inner elongated vessel of special formation adapted= to receive the buttermilk, etc., and having a centrally arranged agitator or stirrer for; stirringthe contents from time to time, to- 2 gether with a cover having circulation apertures for gases, etc. A surrounding vessel auapted to receive the mllk container having an ice holding space, a two-part removable cover and a draining faucet. An outer surrounding case provided with a supporting pedestal or base, adapted to receive the} latter vessel, with intervening msulation; 1' these parts being designed and assembled in the manner illustrated in the drawings, and provided with a withdrawal faucet or discharge arranged for automatic operation, together with other features of improve-; ment and advantage as shall be more fully hereinafter described.

In the drawings-Figure 1 is a vertical. sectional view of the apparatus in its normal condition. Fig. 2 isa cross section on .the line TT. TT. of Fig. 1'. Fig. 3 is an enlarged cross section on the line H1. UT. of

Fig 1. Fig. 4 is an enlarged detail sectional view of the discharge valve for the milk showing it raised by the drinking cup.

The entire apparatus is designed to be set uponany suitable support, as a table, bar, etc., and is provided with a supporting barrel shaped base 2 which may have a continuous bottom' portion 3, as shown, or which may be merely hollow at the bottom with finished edges, as desired. The upper portion of the base is preferably reinforced by rounding the upper edge around an annular wire, as indicated at 4:. The base as thus constructed, preferably of sheet metal,

presents a round smooth appearance, constituting the primary unit of the assembled cooler, and is cut out at one side, as indicated at -5, for clearance of the drinking cup 6, operable with the discharge valve or Specification of Letters Patent. A P t t d D 16, 1913. Application filed December 17, 1912. Serial No. 737,286.

: faucet in the manner hereinafter described.

Set upon the base 2 is the secondary unit of the apparatus, consisting of the barrelshaped vessel 7, also preferably of sheet metal, and which constitutes the insulatin inclosihg frame for the refrigerating vesse The outer vessel 7 is circular in form,

making interfitting engagement with the rounded edge 4 of the base 2, by the annular recess and downwardly projecting portion of the insulating vessel, as indicated at 8. The entireinner body portion of the insulating vessel, except the central bottom part, is covered with an insulating lining 9 of sheet asbestos orother suitable material.

At its upper edge, the insulating vessel 7 is provided with a shouldered portion 10 adapted to receive the upper edge portion of the ice container, the upper outer edge of the insulating vessel being also preferably rounded and reinforced, as indicated at 11, for the purpose of providin a finished edge, and also to receive the e ge portions of the two-part removable cover.

Set within the insulating vessel 7, and resting upon its base by its'own bottom 12,

is the ice containing and milk-vessel-supporting vessel 13, also preferably made of sheet metal, having a contracted base portion 14 terminating in an annular rounded channel 15 for receiving the base of the milk container, then extended outwardly for almost the full diameter of the insulating vessel 7, preferably having one or more annular reinforcing beads 16 and then extending heat insulation; In assembling these parts,

the insulating vessel 7 is originally made of a maximum diameteratits middle portion, with the upper wall portion extending truly cylindrical thereabove, and after the insulation 18 is packed into place, the upper portion of the insulating vessel is drawn or pressedinwardly as clearly shown in the drawings, bringing the upper neckportion into close proximity to the upper portion of the ice container 13. l

The milk container 19, also preferably made of sheet metal, is provided with a generallv mushroom shaped base portion 20 of maximum diameter, rounded at its outer bottom edge to neatly fit into the receiying channel 15 of the base of the ice container,

- but sufliciently loose as to fit to permit of the circulation downwardly to the water space 21, of the water from the melted ice. The bottom 22 of the milk container slopes toward the outlet connection toward one side of the apparatus Within the walls of the contaii'ier, where I provide the discharge valve23. Said valve, which may be in the form of a ball, as shown, or of other suitable form, seats upon a hollow bushing 24 having a crimped engagement with the bot- U tom, as shown, and fixedly connected by a I a container and insulating vessel respectively. By this construction the water at the base 24 and providing an outlet for. the'contents.

lelescopically mounted around the stem extension 28 is a vertically movable sleeve 29 having a plurality of projecting arms 30 for engagement by the upper edge of the cup 6, when lifted, the sleeve 29 having a limited range of movement, and being connected by 'a cross pin 31 with valve stem 32 of valve 23, so as to unseat the valve by raising the cup, the valve seating by gravity when it is lowered. This portion of the apparatus forms the subject matter of a separate application, filed herewith.

For the purpose of withdrawing the melted water from cavity 21 from time to time, I provide a cock or faucet 33 connect ed by screw joint with an outlet nipple 34, each of said parts being shouldered and with intervening packing'35 also assisting in tightly connecting the bottoms of the ice of the apparatus is also capablevof being used. for drinking purposes.

The milk container 19 is very considerably narrower at its upper middle portion,

within the ice container, as shown, for thepurpose of reducing the diametrical cross section of the vessel, effecting a correspond ing enlargement of the surrounding ice conprovided with an annular projecting shoul taining space and with a-resultin'g increase .of the refrigerating eflect. Above its middle portion, the milk container is flared outwardly somewhat, as indicated at 36. and

der 37 adapted to receive, and support the inner annular edges of the two-part cover.

Slightly above the annular shoulder 37, with sufficient intervening space for the cover,

the milk container is diametrically enlarged, as indicated at 38, and then extended upwardly in barrel formation with outwardly bulging sides, like those of the base 2 and insulating vessel 7, providing the third unit 39, constituting the upper portion of the entire apparatus. This part of the milk container, which is entirely. above the refrigerating vessel, serves as a reservoir to contain the fluid which passes downwardly into the refrigerating compartment, as it is drawn off from the base from time to time. The upper portion of the milk container reservoir unit 39 is also rounded by reinforcing annular edge 40, adapted to receive and support the upwardly rounding cover 41, which is pressed around its outer edge to provide a sea-ting or nesting channel 42 within an outer reinforcing bead 43. At its central portion the cover is turned upwardly for a short distance, providinga cylindrical neck 43- adapted to receive and provide a bearing for the stem of the agitator. A finishingcovering cup or cap 44 is set over the central top portion of the cover 41, as

shown, said cup having a series-of circulation apertures 45. The central neck portion of the cover is also provided with similar apertures 46, by which any gases, odors, etc,

may escape from the interior. 7

The ice container and'also the insulating vessel are covered over by two-part cover sections 47, 47, each made preferably in semi-circular form, having inner and outer reinforced supporting edges 48, 49, adapted to rest upon the annular shoulder 37 and edge 11 respectively, and each having a lifting button or stud 50, 50. These covers are also preferably made of sheet metal rounded in symmetrical form-to provide a covering coping, and are preferably provided with an. inner supplementalsimilarly shaped shell 51 riveted or otherwise secured to the outershell, and with an inner refrigerating packing 52, of sheet asbestos or other suitable material,

The agitator or stirrer 53, which may be of any suitable construction, is as shown, of paddle form, made of sheet metal or wood having a plurality of transverse passages or openings 54 for circulation of the fluid. At its bottom, the stirrer is provided with the turning stem 57, which may be conveniently vmade-of a tube flattened at th lower end and riveted, its upper end being indicated at 58, for attachment of a turning handle upon removal of cup 44.

The operation of the device as thus con structed is as follows: Ice having been placed in the ice container-13, filling" the cavity between it and the milk container 19, as indicated, the milk container is filled or partlally filled with milk, which may, when squared, as

- top portions of the milk may be thoroughly commingled, releasing any gases of fermentation, and keeping the milk fresh and sweet, assisted by the circulating apertures at the top of unit 39. By this means milk, especially buttermilk, may be kept free from odor or other objectionable qualities ordinarily resulting from the keeping of a quantity of buttermilk in an ordinary receptacle in which the milk may stand for any length of time. Due to the shape of the milk container Within the surrounding body of ice, the refrigerating action is utilized to the highest degree, the contracted neck portion and flaring surfaces of the mushroom-shaped base presenting ample exposure of the con tents against the gravitating action of the reduced temperature.

The device is extremely clean and sanitary and capable at all times of being thoroughly cleansed, while preventing the possibility of the accumulation of any stale milk or foreign matter. Theseveral parts, being made of sheet metal, stamped or pressed to shape, thereby avoid the necessity of riveted or soldered joints; the entire outer portions of the parts, or the inner portions, if desired, are or maybe covered with enamel or other suitable covering, thereby greatly enhancing the appearance of the device, while its structure generally lends to it a shapely and artistic appearance. It is also extremely economical of ice, due to the insulation of the surrounding vessel, While all of the refrigerating qualities, as well as the melted water of the ice, are utilized.

The advantages of the invention will be appreciated by all those vending or using buttermilk and other liquids; it may be made of any desired capacity; the exterior of the various units may be embellished by any desired ornamentation, lettering, etc., while the material from which the cooler is made greatly reduces its weight while preventing the danger of breakage and resulting leaks.
